WEAR MEMBER SECURED BY COMBINATION OF TABS AND A LOCK, AND TYPICALLY FOR EXCAVATING MACHINERY

摘要

A wear cap for protecting the wearable surface of a structural member includes an outer wear surface and an inner mounting surface. The inner mounting surface is provided with a plurality of tabs and a lock which cooperate to securely attach the wear cap to the wearable surface. The tabs are inclined in a uniform direction at an acute angle to the mounting surface to minimize the amount of travel needed to install and remove the wear cap. The lock has a rigid hub and a shaft. The hub includes a pair of bearing faces which interact with the wear cap and the wearable surface to effectively prevent loss of the wear cap during use.
